Quantum Fisher information and coherence in one-dimensional spin models with Dzyaloshinsky-Moriya interactions
Biao-Liang Ye, Bo Li, Zhi-Xi Wang +2
We investigate quantum phase transitions in spin models using Dzyaloshinsky-Moriya (DM) interactions. We identify the quantum critical points via quantum Fisher information an…
Complete Optimal Convex Approximations of Qubit States under Distance
Xiao-Bin Liang, Bo Li, Biao-Liang Ye +2
We consider the optimal approximation of arbitrary qubit states with respect to an available states consisting the eigenstates of two of three Pauli matrices, the -distance of…
Multiplex-controlled phase gate with qubits distributed in a multi-cavity system
Biaoliang Ye, Zhen-Fei Zheng, Chui-Ping Yang
We present a way to realize a multiplex-controlled phase gate of n-1 control qubits simultaneously controlling one target qubit, with n qubits distributed in n different cavities.…
Quantum correlations in critical system and LMG model
Biao-Liang Ye, Bo Li, Xianqing Li-Jost +1
We investigate the quantum phase transitions for the spin-1/2 chains via the quantum correlations between the nearest and next to nearest neighbor spins characterized by nega…
